Project Everest

Refrigiration Station ?

There is a demand at the moment all over the world for a refrigeration method that does not use electricity or uses a low amount of it. In Cambodia we have come to realize that people, whether they live in the city or in rural villages, don't use anything to store food. Because of this, almost everyone is buying food for every meal everyday and wasting food due to the fact that they cant keep leftovers and much more.

For this problem a few of us are trying to come up with a solution. To give you a better idea of the situation here are some bullet points:

  • people here are using very inefficient eskys and ice
  • the ice usually melts in a few hours
  • the average expendable income is about 50$ a month
  • ice costs about 0.25 $
  • most of the rural area don't have electricity and for its fairly expensive for people who do have access
  • mainly people use electricity for a few lights and maybe a few fans
  • if the solution uses electricity as much as a lamp that's ok.

Also, we have been looking at evaporative coolers, changing chest freezers to fridges and making a super efficient eskey. We've drawn a few designs on the latter and a few of them are based on the eskey being under ground.

please have a read and if you can think of any other ideas, let us know.

please don't hesitate to ask any questions about the project.

Venture On !!

Sweet, awesome problem to attack!
For me, the obvious solution seems to be solar powered refrigeration. The idea of turning heat into cool through photo-voltaic cells is kinda ironic to.
What kind of financial status are we looking at in the communities where these solutions are needed?

So regarding the financial status, we are looking at people who have about 50 $ a month worth of expendable income.

Super interesting problem space.
A band-aid solution would be to have some community-based storage/refrigeration solution, e.g. a refrigerated shipping container. This would reduce cost per user, making it more accessible.
But obviously this isn't a long-term solution.

Maybe have a look at what options there are in terms of natural/eco insulation materials. This would be sustainable, and would lessen the cost of electricity used for refrigeration.
